Sorry to disagree with you here, Atreides, but in each instance where Apple has gone 100% independent of the grid, it has saved millions of dollars each year in energy costs they would have expended in utility expenses. In addition, Apple has actually now, in their services area, a line item for sales of energy INTO the grid when they don't use all of the energy their systems generate. The energy independence has become a net profit generator (excuse the pun) albeit a small one in comparison to the huge profit generators of their hardware.
I do, also, believe that Apple has taken advantage of the tax credits for solar and alternative fuels in installing these generation facilities. They would be foolishand in violation of their financial obligations to their investorsnot too. Some Liberals would assert that using such tax credits is requiring other tax payers to "foot the bill" in that Apple is somehow (read immorally) not sending in as many tax dollars to the IRS as they would have were they taking advantage of these tax credits (read dishonest tax loopholes when a rich corporation uses them). I take the other view, the money we send to the government is OURS that we are voluntarily contributing to the general weal, not the government's that the government is claiming back from us. Taxes are never a government cost and cannot be counted as an expense that other taxpayers "foot the bill for" when anyone takes advantage of the laws Congress has written to lower their taxes.
“it has saved millions of dollars each year in energy costs”
Totally disagree. Without taxpayer monies there isn’t a renewable energy that is profitable.
